Near term through tonight ...

the region will be between high pressure to the east southeast and a
trough of low pressure to the north northwest through tonight. This
pattern will continue a moist south southwest low level flow. The
flow in the mid levels is expected to be light and from the west
northwest. Storms will develop inland this afternoon, initiated by
diurnal heating. Activity which develops will then slowly work
toward the east through the afternoon, with a south southeast
component to the individual cells due to winds aloft. The slow
movement of these storms will lead to locally heavy rainfall. Strong
winds from brief downbursts will be possible. The low level flow
will help keep the east coast sea breeze pinned near the coast,
likely not making it much past i95.

Convection is expected to dissipate this evening, with skies
clearing overnight.

Another hot day forecast today, with temperatures above normal. Heat
indices to reach 104-107 this afternoon, just shy of heat advisory
criteria of 108.

Short term Thursday through Friday night... Mid-level high
pressure ridge over the area will start to weaken while drier air
aloft advects into NE fl from the atlantic. This should result in
slightly better rain chances over SE ga with less coverage over
ne fl. Surface ridge to the south will produce a light SW flow
with seabreezes moving inland during the afternoons. Slow moving
storms may result in areas of heavy rainfall with isolated strong
storms possible where cell mergers occur. Temperatures will be at
or slightly above average with daytime readings reaching the
low mid 90s.

Long term Saturday through Tuesday... A weakness will develop in
the subtropical ridge aloft during the period. Moisture levels
will be near average level with inland moving seabreezes. Expect
scattered to numerous p.M. Showers and storms each day. Temperatures
will be at or slightly above average through the period.

Marine The region will be between high pressure to the east
southeast, and a low pressure trough to the northwest into early
next week.

Rip currents: SE ga: low risk through Thursday
ne fl: moderate risk through Thursday

Aviation 06z TAF period... Patchy inland fog will be possible
early this morning, which could cause a period of restrictions at
kgnv and kvqq. Scattered thunderstorms expected this afternoon,
which could lead to restrictions at area TAF sites.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
